DXE-AOK-80M
80 Meter Add On Kit for the Hustler® 4-BTV Vertical
Antenna adds 80 meter coverage without giving up any existing band coverage.
The
DXE-AOK-80M
kit is tunable to operate across a small segment of the 75/80m band with an
SWR of 1.5:1 or less. Larger frequency excursions are easily made by lowering the antenna and
adjusting the length of the top rod. A
DXE-TB-3P
Tilt Base for Hustler® BTV Antennas makes
this a simple job.
No disassembly of the existing antenna is required, simply add this
DXE-AOK-80M
kit which
includes the Hustler RM-80S and a three-bladed spider assembly to the top of the existing
installation, make some minimal tuning adjustments and you're on the air with an additional band.

Hustler® RM75/80 Resonator with Large Corona Ball Whip

Hustler three bladed Spider Assembly for 80 meters
Tools Required
Allen Wrench - supplied with RM 75/80 Resonator

Installation
On your existing Hustler® 4-BTV, there may be a plastic cap on the threaded rod
protruding from the top of the vertical antenna as shown to the right. If so, remove
the cap. Ensure the existing threaded rod is in place, this is needed to mount the
new 75/80 Meter Resonator.
The three bladed spider assembly has three strips of metal welded to an element
clamp. Using pliers to hold the welded area, carefully bend the three bladed spider legs as shown
below.
Install the three bladed spider just below the top of the antenna as shown to the right
Using the supplied Allen Wrench, loosen the two Allen set screws far enough to allow insertion of
the whip antenna about 4" beyond the set screws as shown below. Snug the Allen set screws in
place to hold the whip in place. During tuning, you will be making adjustments to this length.
